What would be the best way to add a comment to a table entry
On my dialog form I have a jtable, the table is populated by user selections. I need to give the user to add a comment about a selection on the table. So i am thinking what if I create a array of strings and then I get the selected Row from the table - pop a comments dialog and save the typed string to the String Array at the index of the selected Row. That way when I need to recall the information I can just run through the table list and the string array to get both information. Does that sound OK? Also I am wondering how I would show that a comment as been added.

Do you happen to have a custom TableModel?

I am using a class to format my arraylist.
Then I am using a add method in a seperate class to build my List
If there a way to add a String value to the RevDataset class so when the string is being built with the add method it would also be adding a null string to each one entry
the list would look something like
tcRevision, selectedDataset, comment
instead of
tcRevision, selectedDataset
That way the comment would be also available in the table
public class RevDataset {
TCComponentItemRevision rev;
TCComponentDataset componentdataset;
//////////////////////////////////////////////////////////////////////////
// //
// Constructor //
// //
//////////////////////////////////////////////////////////////////////////
public RevDataset(TCComponentItemRevision tcRevision, TCComponentDataset selectedDataset) {
rev = tcRevision;
componentdataset = selectedDataset;
}// end Constructor
//////////////////////////////////////////////////////////////////////////
// //
// getDataset() //
// //
//////////////////////////////////////////////////////////////////////////
public TCComponent getDataset() {
return componentdataset;
}// end getDataset()
//////////////////////////////////////////////////////////////////////////
// //
// getRev() //
// //
//////////////////////////////////////////////////////////////////////////
public TCComponent getRev() {
return rev;
}//end getRev()
//////////////////////////////////////////////////////////////////////////
// //
// equals() //
// //
//////////////////////////////////////////////////////////////////////////
public boolean equals(Object o){
RevDataset p = (RevDataset) o;
if(rev.equals(p.getRev()) && componentdataset.equals(p.getDataset())) {
return true;
}
else {
return false;
}
}// end equals()
}Then I am using a add method in a seperate class to build my List
//////////////////////////////////////////////////////////////////////////
// //
// add() //
// //
//////////////////////////////////////////////////////////////////////////
public void add(TCComponentItemRevision tcRevision, TCComponentDataset selectedDataset){
RevDataset pp = new RevDataset(tcRevision,selectedDataset);
if(!rds.contains(pp))rds.add(pp);
fireTableDataChanged();
}// end addIf there a way to add a String value to the RevDataset class so when the string is being built with the add method it would also be adding a null string to each one entry
the list would look something like
tcRevision, selectedDataset, comment
instead of
tcRevision, selectedDataset
That way the comment would be also available in the table
It wouldn't necessarily be a good thing to add it to the RevDataset class. Why don't you just add it when you build the TableModel?
ASKER
Can you show me a example of to do that?

but also the user will be adding a comment to a specfic entry on the table. If we add it to the table will we still be able to pull the information out?
The table IS the TableModel effectively. The only sense in which they differ is if/when you decide to hide columns from view. A JTable is just a view of a TableModel

You did answer the question and for that I thank you. After learning more about what I was wanting, I understand that the question was not correctly asked.

OK
